Has the peace process in Afghanistan collapsed?

Trump cancels meeting with Taliban at Camp David over peace deal after car bombing in Kabul kills US soldier.

Talks to end the 18-year war in Afghanistan appeared to be making progress, but the negotiations are now at risk.

The Taliban and the United States came up with a draft deal after nearly a year of discussions in Qatar, and the US's chief negotiator sounded optimistic when he revealed the details to the Afghan president last week.

However, US President Donald Trump tweeted on Sunday that he cancelled a secret meeting with Taliban leaders and the Afghan president at Camp David in Washington, DC.

Trump said he doubted the armed group wanted an agreement after a Taliban car bombing killed an American soldier and 11 other people in Kabul on Thursday.
